HARRow.

SPECIFICATION forming part of Letters Patent No. 742,531, dated October27, 1903. Application filed December 12, 1902. Serial No. 134,956. (Nomodel.)

To a/ZZ whom it may concern:

Be it known that I, Onvrs CURTIS VAUGHN, a citizen of the United States,and a resident' of Chicago, in the county of Cook and State of' r'Illinois, have invented certain new and useful Improvements in Harrows;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its obj ect to provide a harrow that combinesiiexibility, simplicity, and economy 0fconstruction with durability andefficiency; and it consists of the following described construction.

Figure l of the drawings shows a top view of a section of my harroW.Fig. 2 shows an end view of one rail of a section of the harrow withparts attached. Fig. 3 shows a fragment of a rail of a section withadjusting devices in place, and Fig. 4 is a side elevation of one of thelinks.

My harrow may consist of one or more sections, each section consistingof a plurality of rails A and each rail holding a plurality of teeth B.The rails are preferably cylindrical in form and constructed of Wood ormetal. The teeth may be inserted in the rails in a manner so that theydo not register in path of travel of the preceding teeth. The object ofconnecting the rails together at their respective ends is accomplishedby means of links C, the latter for economy of construction anddurability being preferably handforged from one piece of steel. The linkC is bent so as to form a ring G, through which the end of rail A isinserted, as shown in Fig. 2, and a loop C" at one end and-aheelgC' atthe other end, the hook C. of one link be'ng adapted to engage the loopC" of another linl Secured to the two opposite sides of the rails A bymeans of bolts e are clips E and F. The clip E is formed of one piece ofmetal having ends in curved form fitting on the rail and a raisedcentral portion wherein is an elongated vertical opening E', throughwhich the link C passes, and the said latter clip serves to limit thelink C in lateral motion and at the same time to limit its verticalmotion. The clip F, which is secured to the opposite side of the rail,is also made of one piece of metal bent so as to form two lugs, leavinga central groove f, into which the link C is inserted, the two lugs onthe l two sides limiting the lateral motion of the link. By thisconstruction the connecting device does not interfere with the locationof the teeth in the rail, as the teeth may be inserted along the rail atany point, the teeth being entirely separated from the connectingdevice.

One of the advantages of my harrow is that it 'adjusts itself todifferent angles When hauled from different ends, it being necessarywith my construction to form the last link D on one end of the harrow ofa solid piece of metal, so that the last link has a loop d at its innerend and a loop d at its outer end and a ring G for the rails at bothends, as shown in Fig. 4. This arrangement is necessary in order toproperly adjust the angle of the teeth in the last rail.

Another advantage found in my device is that one section of a harrow maybe used to an advantage or the entire harrow may be extended to covergreat space of ground laterally by securing my connecting device atvarying distances from the ends of the rails, as shown in Fig. 1 of thedrawings.

- It will be seen that the harrow when hauled from one end will give theteeth a vertical position and that when hauled from the other endpermits the teeth to incline away from the direction of the motion andbeing made flexible by the use of the hook-coupling will adj ust itselfto uneven ground and free itself from obstruction.

What I claim, and desire to secure by Letters Patent, is-

1. In combination in a harrow,'a tooth-holding rail, a rail adjustingand connecting device, consisting of a link formed from one piece ofmetal and having a ring and a loop at one end, and a hook at the otherend, two clips, means for securing said clips to a rail, one of saidclips limiting both the vertical and lateral motion of said link, andthe other limiting its lateral motion, substantially as set forth.

' 2. In combination in aharrow, a tooth-holding rail, a link adapted tot loosely around said rail, having a loop at one end and a hook at theother end, two clips, one of which is bent upon itself, forming lugs,the other having curved ends fitting on the rail and having a raisedcentral portion, and an oblong ICO vertical openingin said centralportion,means for securing said clips to a rail so as to limit thevertical and lateral motion of said link, substantially as set forth.

3. In combination in a harrow, a railadjusting and connecting devicecomprising a link bent upon itself, forming a ring, a loop and a hook, atooth-holding rail, clips secured tol the latter for engagement Withsaid link, limiting the vertical and preventing the lateral motion ofthelatter, snbstantiallyas set forth.

4. In combination in'a barrow, a tooth-holding rail, a link formed witha loop at one end and a hook at the other end, and a ring near said loopfitting loosely over said rail, clips rigidly seenred to the latter forengagement with said link to limit the lateral and vertioal motion ofthe latter, substantially as set forth.

5. In combination in aharrow, a toolhhold 2o ing rail, a link formedwith a loop at one end and a hook at the other end, and a ring near saidloop adapted to t loosely over said rail, another link formed with aloop at both ends and two rings near the said loops adapted to fitloosely over` the rails, and for engagement with the former link, twoclips rigidly secured to each of said rails for engagement with saidlinks and limiting the lateral and vertical motion of the latter,substantially as set forth.

In testimony whereof I ax my signature in presence of two Witnesses.
